were calculated for upgradient surface water stations SW-1 and SW-2,the increasing trend in turbidity at surface water station SW-3 is considered reflective of regional impacts and/or non-facility related. 6.4 COMPLIANCE RECORD Historically, low-level VOCs have been consistently detected in leachate well MW-IA and sporadically in downgradient groundwater monitoring wells at the French Camp Landfill. During the third quarter 2006 monitoring period,non-statistical indication of a release was identified in well MW-9A as a result of the detection of TCFM above the PQL, and the results from the retest samples confirmed the presence of TCFM in well MW-9A. TCFM is a common landfill gas constituent. The perimeter soil-pore gas probes will be monitored quarterly for fixed gases and VOCs for one year to evaluate landfill gas impacts at the site. During the 2006 monitoring year the French Camp Landfill did not accept waste and the final cover construction was completed in November 2006. No NOW were issued by the LEA or CIWMB during the 2006 monitoring year and the site is currently in compliance. 7.0 SUMMARY Groundwater quality conditions beneath the French Camp Landfill during the fourth quarter 2006 monitoring period are generally similar to those observed in previous monitoring periods. During the fourth quarter 2006 monitoring period, inorganic CLs were exceeded in DMP wells MW-6A, -9A, -913, and MW-10A. In addition, organic constituent results indicate concentrations of TCFM exceed the PQL in the sample collected from well MW-9A. Pursuant to WDR Order No. R5-2004-0159 Section E(19)(b)(2)a non-statistical indication of a release from well MW-9A has been verified and the RWQCB was immediately notified of the release. The results of water quality analyses completed for leachate monitoring well MW-2 indicates that no VOCs were detected in the sample from this well during the current monitoring period. The results of water quality analyses completed for surface-water monitoring stations are generally consistent with previous results. During the current monitoring period, CL exceedances were noted for the magnesium concentration in the sample from station SW-3, and nitrate as nitrogen concentrations in the samples from stations SW-1 and SW-2. Trend analyses indicates that turbidity at surface water stations SW-1, SW-2, and SW-3 depict statistically significant increasing trends. Given that turbidity exhibits a statistically significant increasing trend at background surface water stations SW-1 and SW-2, the increasing trend in turbidity at SW-3 is unlikely to be indicative of an impact from the facility.
